I don't know if this issue has already been answered, but I can't get my head around it. I used to do this in Illustrator, and there it was simply a matter of clicking "bring forward/bring back" etc.
We are about to start digitizing a lot of orthophotos of archaeological scenes generated in Agisoft Photoscan Pro. The excavations contains A LOT of wood and other artefacts. Various orthophotos covers several vertical layers (as we have dug down, each layers has been documented).
My question is as follows:
I have been digitizing two overlapping orthophotos, but the main problem is, that many of the artefacts or pieces of wood, overlap each other. I would really like to avoid, having to create layers for EACH artefact, and thus being able to contain fx all "Mandibles" in its corresponding Shapefile/layer. So, that the mandibles with the most positive Z-values, wouldnt be overlapped by wood with lower Z-values, simply because the layer for wood is above mandibles in the layers list.
Would it make a difference, if each polygon was assigned a Z-value (possibly extracted from a DEM)?
Any suggestions?
